The development of theoretical models and experimental methods of cell mechanics are actual task. On the bases of the shell theory we consider the elastic properties of the cells and compeer them with the experimental resuts which was received using atomic force microscopy (AFM) date. The experimental calculations were made on the bases of the Herz model.(More)
Atomic force microscopy (AFM) is a unique method to study a single cell surface layer as a biocomposite. This chapter focuses on the advantages of two AFM modes, namely force spectroscopy (providing the information about local elastic properties of cells) and lateral force microscopy (LFM, revealing mechanical heterogeneity of cells surface), to make(More)
To evaluate toxicity of silver nanoparticles synthesized by using the reverse micelle formation method, the effects of nanoparticles on lipid peroxidation and morphological changes of cell membranes in human lymphocytes were studied. It was found that under the influence of nanoparticles a reduction in cell viability and formation of excessive levels of(More)
Redox regulation and carbohydrate recognition are potent molecular mechanisms which can contribute to platelet aggregation in response to various stimuli. The purpose of this study is to investigate the relationship between these mechanisms and to examine whether cell surface glycocalyx and cell stiffness of human platelets are sensitive to the redox(More)
Treatment of HIV infection by gene therapy is a promising tool for combating AIDS. One of the primary limitations of gene therapy is the effective delivery of nucleic acids to the target cells. Dendrimers are nanoparticles that are increasingly being used as nucleic acid vehicles. We have synthesized "Si-C" amino-terminated carbosilane dendrimers(More)
The effect of NO donors (sodium nitroprusside, S-nitrosoglutathione, dinitrosyl-iron complexes) on the functional and mechanical properties of human platelets and red blood cells has been investigated. It has been established by atomic force microscopy that NO donor-induced platelet disaggregation is accompanied by changes in the elastic properties of(More)
Myeloperoxidase (MPO) is a heme-containing enzyme released from activated leukocytes into the extracellular space during inflammation. Its main function is the production of hypohalous acids that are potent oxidants. MPO can also modulate cell signaling and inflammatory responses independently of its enzymatic activity. Because MPO is regarded as an(More)
